Re: Acorn Controller: Z and 4th Axis Closed Loop Stepper Not Working

One final note, all my axes are on H2 and H3 headers. The DB25 wasn't needed.

Re: Acorn Controller: Z and 4th Axis Closed Loop Stepper Not Working

Hi everyone, discovered what my issue was and of course it was equipment related. The CL86Y I was using to test the Z and A axes had an issue with the dip switches. Before I discovered that, I Ohm'd out all connections and checked continuity between all cables and pins, checked voltages etc. I also ...

Re: Acorn Controller: Z and 4th Axis Closed Loop Stepper Not Working

Hi Uwe, Thanks for that advice. I'll recheck everything. As I stated, "Clearly something I'm doing wrong but what? ". I am not familiar with the "Position Following error" setting, but will locate it. I have not tried the tuning SW since it is recommended that one get the drives ...

Re: Acorn Controller: Z and 4th Axis Closed Loop Stepper Not Working

Hi Uwe, I set my pulses per rev to 1600 when I was using my conventional steppers vs the closed looped ones. I did set the pulses per rev to 4000 when using the closed loop steppers. I also tried all values below 4000 and set the appropriate dip switches on the CL86Y drivers but still no movement. A...

Re: Acorn Controller: Z and 4th Axis Closed Loop Stepper Not Working

I have a breakout board but shouldn't a rather expensive controller work on all ports, especially H2 and H3? If it works on the DB25 then Ok but why Centroid wouldn't mention this is strange to me. The DB25 uses 5V logic vs 24V logic (what I am using on H2 and H3).

Acorn Controller: Z and 4th Axis Closed Loop Stepper Not Working <self resolved>

I have a strange thing happening with my Acorn setup. I am using closed loop stepper motors on all four axes. The stepper drives are Stepperonline CL86Y and the motors are Stepperonline NEMA 34 types 34HE46-6004D-E1000. These were setup as 4000 pulses/rev. X and Y axes work perfectly but the Z and A...
